Latest Update: 07 July 2015
The Mono Bucket met mast foundation was completely removed from the site by DBB Jack-Up Services by reversing the suction process. By applying pressure into the Mono Bucket the foundation was lifted from the seabed, leaving it unmarked. The met mast was no longer needed.
The Mono Bucket was one of the very first to be employed and has been in situ for 6 years, having been installed in March 2009. The weight of the foundation is 165t with a total height of 38meters. It was installed to within 0.1 degree of true vertical and with a 0.6m stick-up.
